Spectrally equivalent preconditioners for mixed hybrid discretizations of diffusion equations on distorted meshes

In this paper, we investigate the spectral properties of condensed matrices in mixed hybrid discretizations of the Neumann boundary value problem for the Poisson equation on distorted meshes...
